      Overview Manuals Common Applications Product Precautions
      Schneider Electric 140CPU43412A provides program execution and Modbus or Modbus Plus coordination in a documented legacy Modicon Quantum controller in a documented Modicon Quantum installation.
      • 80486-class 66 MHz processor
      • 896 kB RAM
      • Two Modbus ports
      • One Modbus Plus interface

      The component remains matched to its documented cabinet position, power source, interfaces and approved engineering configuration. Commissioning restores that architecture and verifies the affected control or communication function under controlled conditions.

      Important Notice: Confirm 140CPU43412A, its exact Modicon Quantum host, power source, installed position, interfaces, configuration, diagnostics and controlled acceptance evidence before release.
